INJECTOR-CONDENSER.

SPECIFICATION forming part of Letters Patent No. 257,629, dated May'Q, 1882. Application filed January 23, 1582. (No model.)

To all whom it may concern:

Be it known that I, JEROME WHnELooK, of the city and county of Worcester, and State of Massachusetts, have invented certain new and useful Improvements in Injector-Comlensers for Steam'lflngines; and I dohereby declare that the following specification, taken in connection with the drawings furnished and forming a part of the same, is a clear, true, and complete description of the several features of myinvention.

In my prior Letters Patent, No. 242,088, dated May 24, 1881, I show a condenser of the class to which my present improvements are applicable, although they may be profi tab] y employed with condensers otherwise constructed. The objects now sought by me are to obtain a uniform discharge of water through or into the condenser-nozzle when a minimum supply of water is employed; also, to provide for the flushing of the water-chamber, so as to remove the accumulated impurities from time to time; and also, to cheaply provide for a properly shaped and smooth-surfaced nozzle within the usual discharge-pipe.

After a full description 'of a condenser embodying my several improvements, the features deemed novel willbe designated in the several claims hereunto annexed.

Referring to the drawings, Figure 1 is a vertical central section ot'a condenser containing my improvements. 'Fig. 2 is a horizontal section of same on line :10.

The exhaust-pipe A communicates with the engine-cylinder in the usual manner. Thewater-induction aperture B communicates with The annular waterchamber 0 is novel in its character, in that the annular lip a is elevated above the bottom of said chamber, thus affording an annular sedimen t-trap, b,within which all earth ym atters settle, instead of being directly forced in to the annularjet-aperture between said lip a and the adjacent outer surface of the tapered annular mouth-piece c. The jet-aperture at the-lip a is, as commonly, of less width than it is below the mouth or entrance, and therefore floating matter in the water is not liable to obstruct any portion of the jet-aperture by entering and becoming wedged therein. For flushing the trap b, I have provided a vertical pipe, (I,

tapped into said trap opposite the entrance to the water-chamber, and by means of a cock, 0, the contents of the trap may be discharged from time to time through said pipe and cock. As here shown, said pipe at its lower end is provided with an elbow leading into the discharge-pipe f, which communicates with the hot-well. The hot-well being usually of snfficient depth to provide for connecting theboiler therewith, at a point midway between thebottom thereof and the water-line therein, permits the heavy matters to settle in said well and the floating matters toremain on top without any of them being liable to be carried to the boilers.

It is desirable that the internal conical form of these injector-condensers be of considerable length for obtaining the best results, and this I accomplish economically by locating within the discharge-pipe a conical nozzle, g, the upper end of which is coincident with the interior of the cast-iron shell II, in which thewater chamber and trap b is formed, and to which the steam nozzle or mouth-piece c isconnected, this latter having two annular extensions secured thereto, substantially as in my priorLetters Patent, hereinbeforc referred to. The lower end of this nozzle g is much smaller than its upper end, and may be slightly submerged by water standing at its level in the hot-well, or slightly above the water-line, as may be preferred. Instead of having an expensive castin g to provide for this conical extension, I prefer to construct the nozzle g of sheet-iron, and I thereby obtain a smooth and comparatively frictionless interior surface at low cost. This conical extension, separately constructed and located within the dischargepipe, has value, regardless of whether said nozzle be composed of sheet-iron or' cast-iron, because it enables me to make the cast-iron main shell of the condenser, including the clampin g-rin g i, very light and of short length, and it is consequently cheaply molded and cast; and as the nozzle 9 is located Within a.

piece of ordinary straightpipe, f, it need notbe flanged to afford bolt-sockets, and being externally protected it may be extremely light and inexpensive.

It will be seen that in operation the discharge of water over the annular lip ainto supply of'water than would be the case if the month of the jet-aperture were located below the water-entrance, as heretofore, in which case the portions of the aperture on each side of the water-entrance would be fully supplied, while on the side farthest from said entrance there would be little or no water.

Iain aware that in pumping-condensers an elevated annular lip Within the water-chamber has heretofore been employed 5 but in such condensers the water is forcibly drawn into the condenser bythe forward movement ofthe pump-piston, which necessitates that the water chamber and its supply-pipe be always filled with water, for it not thus filled the pump could have no suction control of the water, whereas in an injector-condenser it is frequently desirable, and sometimes necessary, to operate with but little water, and therefore when the water-chamber is supplied with only water enough to barely liow over the top of the lip it will always be distributed with uniformity at all points of the lip and be presented so as to surround the entering column of exhauststeam and be enabled to perform condensing duty fully proportionate to its quantity.

Having thus described my invention, I claim as new- .1. In an injector-condenser,thecombination, with the water-ehamber'having an elevated annular lip, a cone projecting downward within said lip, of a conical shell extending below said cone and water-chamber, and a discharge pipe connected to the lower and small end of said conical shell, substantially as described.

2. The combination, with the water-chamber in an injector-condenser, of asediment-trap and a flush-pipe, substantially as described;

3. The combination, with the conical main shell in an injector-condenser and a dischargepipe connected to the lower end of said shell, of a tapered nozzle extending downwardly within said discharge-pipe, and in comm unication at its 'upper end with the interior of the conical shell, substantially as described.
